Question

Which is the correct arrangement of muscle structures from biggest to smallest?

• A. Myofibril, myofilament, muscle fascicle
• B. Muscle , fascicle, myofibril, myofilament
• C. Myofilament, myofibril , fascicle, muscle
• D. Fascicle, myofibril, muscle , myofilament

Answer 1

The correct option is B

Muscle , fascicle, myofibril, myofilament

In a muscle myofilaments are arranged in bundles called myofibrils which in turn are bundles in a fascicle and many such fascicles make up a muscle.And the muscle is covered by the perimysium, the fascicle is covered by the epimysium,the myofibrils are enclosed by the endomysium and finally the myofilament are enclosed by the sarcolemma.
